A macro call can have only one piece of nested content. You had to
pass in the JavaScript as a parameter to the macro. Unfortunately,
there's no syntactical sugar for passing in anonymous macros as
parameters, so what you have to do is:

  <#macro myJSGenerator>
    ...
  </#macro>
  <@page javascript=myJSGenerator>
    ...
  </@page>

Then inside the page macro you had to do something like:

  <head>
     <#if javascript?is_directive><@javascript/><#else>${javascript}</#if>
  </head>

so now the javascript parameter can be a string or a macro that prints
javascript.
